CC2640R2F: Bidirectional Audio : HW setup

Hello guys !

I would like to run some tests with "peripheral_bidirectional_audio" and "central_bidirectional_audio"  BLE applications  .

I think I need the BOOSTXL-AUDIO on both sides stacked on the CC2640R2F LP  .

Can you confirm that this is the HW needed to run both the applications ?
